Hi Del, I've been testing the script switching technique for the last week on our non prod system (TSM2) and it seems to be working well. Set REPLSERVer tsm1 UPDate STGpool DIR_POOL_TSM2 PROTECTstgpool=DIR_POOL_TSM1 protect stgpool DIR_POOL_TSM2 maxsessions=2 wait=yes replicate node DATAMOVER2 maxsessions=2 wait=yes
Set REPLSERVer tsm3 UPDate STGpool DIR_POOL_TSM2 PROTECTstgpool=DIR_POOL_TSM3 protect stgpool DIR_POOL_TSM2 maxsessions=2 wait=yes replicate node DATAMOVER2 maxsessions=2 wait=yes Are there any technical reasons behind "IBM does not recommend the switching technique" statement? Another thought came to my mind - circular replication - TSM1->TSM2->TSM3->TSM1 - I know this will double replication traffic over the WAN but will it be supported by IBM?
